MINE-LOCOMOTIVE.

SPECIFICATION forming part of Letters Patent No. 633,064, datedSeptember 12, 1899.

Application filed March 20,1896. Serial No. 584,074. (No model.)

To (LM whom it may concern:

Be it known that we', DAVID L. BARNES, a resident of Chicago, Illinois,and WILLIAM P. IIENSZEY, a resident of Philadelphia, Pennsylvania,citizens of the United States, have invented certain Improvements inMine-Locomotives, of which the following is a specification. v

The object of our invention is to construct an electric locomotiveespecially adapted for use 1n mines.

One of the main features of the invention is the utilizationV of t-hemotors as part of the frame of the locomotive..

Referring to the accompanying drawings, Figure l is a side view of ourimproved electric mine-locomotive- Fig. 2 is alongitudinal sectionalview. Fig. .5 is a plan view with the weights removed. Fig. et is atransverse sectional view on the line 4 4, Fig. 3. Fig. 5 is atransverse section on the line 5 5, Fig. 3. Fig. G is a detachedperspective view of one of the motors and its bracket.

A A are the two electric motors, and on the frames of these motors areprojecting bearings a, the bearings of one motor alternating with thebearings of the other motor, so that the axle B will be journaled inboth sets of bearings. Each bearing a has an upper and lowerbearinghblock d d2 of the ordinary construe tion, and each bearing isprovided with cups for lubricants. The shafts A of the motors are gearedto the axle B through pinions d2 and gear-wheels a4, (shown by dottedlines in Figs. 2 and 3,) so that it will be seen that poweris applieddirectly to the central axle B.

On each motor'frame A are secured brackets A2 by bolts a5, and on thesebrackets are formed the pedestals A3 for the boxes b of the axles B B2.On the several axles B B B2 are the traction-wheels l). The een ter pairof wheels are plain, while the end wheels are iianged. Each wheel has acrank-pin b2, and these crank-'pins are coupled by connectingrods B3 B4.The connecting-rod B3 is coupled directly to the connecting-rod B4 by apin lf. (Shown clearly in Fig. l.) Power is applied from the motorsdirectly to the central axle B and is applied indirectly to the axles B'B2. It will be seen that the three axles are independent as regardsvertical motion, as the hinge-joint formed by the axle B and thebearings on the motor-frames allows the parts to yield to a certainextent.

Extending over the wheels from end to end of the locomotive are twobeams D, curved at each end so as to conform somewhat to the shape ofthe end wheels, and these beams carry the two platforms D', one at eachend. The frames are tied together by cross-bars D2, and on thesecross-bars are 4brackets d, between which and theboxes b' for the axlesB B2 are springs d', so that the frame composed of the longitudinalbeams D and cross-bars D2 is supported on the axles B B2 through themedium of the springs. The brackets A2, which are bolted to themotor-frames A, are connected to the cross-bars D2 by suspensionrodsThus the outer end of each motorframe is suspended from the framecomposed of the beams D and cross-bars D2. In order that the pullingstrain may be transmitted directly from the motor-frame to the platformD', we couple the motor-frame to the platform by links F, secured to theparts by pins f. The links have sufficient play so that a certain amountof lateral motion can be given to the parts independently, yet when thestrain is placed upon the rear platform the power will be exerted directfrom the axles through the rearlbracket and the links. The platforms areso shaped thatl the operator can sit upon .the floor and place his limbsunder the axle of the adjoining bracket, the hood D3 being of asufficient height to allow the operator to sit with comfort.

On each side of the platform D' are the sandboxes G, having spouts g.These sand-boxes may be arranged in a diiferentmanner without departingfrom our invention. A controller of the ordinary construction may bemounted on each platform within reach of the operator.

The brake-shoes l, which are mounted between the Wheels, conform tothem, as shown, so that when they are drawn up they will bind upon bothwheels. These brake-shoes are connected by rods z' to arms 'i' of leversi2 on a stud mounted in bearings secured to the frame D. The arms i3 ofthe levers are connected to rods t, coupled to rock-shafts I', and onthese rock-shafts are arms I2, which IOO span the vertical shafts I3,having the handwheels The lower ends of the vertical shafts I3 arethreaded and adapted to threaded bearings t6 on the platforms D', sothat on turning the hand-wheels the shaft I will be rocked. The openingsin the rods t4 for the pins t7 of the short arm of the rock-shaft I' areelongated, so that the brakes can be operated from either end. Thevertical shaft I3 at one end has a right-hand screw-thread and the shaftl3 at the opposite end has a left-hand screwthread, one shaft beingraised to put on the brakes and the shaft at the'opposite end is loweredto put on brakes. It will be understood that the brake mechanism maybemodiiied without departingfrom the main feature of our invention.

If there is not sufficient traction, we may use weights M, which restupon the frames D D and extend from one side to the other, as shown inFig. 4. These Weights may be placed at any point desired on the frame.

lVe claim as our invention- I. The combination in an electriclocomotive, of the axles, an electric motor hung to one of said axles,its armature-shaft being geared thereto, extensions on the motor, boxesadapted to the extensions and to the axle, a frame resting on the boxesand from which the free end of the motor is suspended, substantially asdescribed. 4

2. The combination in an electric locomotive, of the centralaxle,drivingwheels thereon, electric motors pivoted to the driving-axleand geared thereto, said motors haring extensionsin which the otheraxles are mounted, substantially as described.

3. The combination in an electric locomotive, of thecentraldriving-axle, wheels thereon, electric motors adapted to drivethe axle, bearings projecting from said motors, said bearings beingalternately arranged on the axle, substantially as described.

4. The combination in electric loco motives, the driving-axle, itsWheels, motors pivoted to the axle and geared thereto, extensions oneach motor, boxes carried by the said extensions, axles adapted to theboxes and a frame extending over the motors and their extensions andresting upon the boxes and connected to the extensions of the motors,substantially as described.

5. The combination of the central drivingaxle, its wheels, motorspivoted to the axle,

extensions on each motor, boxes adapted to the said extensions, axlesadapted to the boxes, wheels on said axles, frames extending over themotors and rest-ing on springs mounted on the boxes and platformssecured at each end of the frame and connected to the extensions of themotors, said extensions being suspended from the said frame,substantially as described.

6. The combination in a mining-locomotive, the central axle, wheelsthereon, axles at each side of the central axle and having wheels, saidwheels being coupled to the central wheels, motors pivoted to thecentral axle and geared thereto, each motor having an extension, boxesadapted to said extensions, platforms at each end of the locomotive andon a line with the motors and their extensions, curved frames secured tothe platforms, springs mounted on the boxes and supporting the curvedframes and the platforms, and suspension-rods extending from the frameto the motors, substantially as described.

7. The combination in a mining-locomotive, of the central axle, motorshung thereto on each side, rigidextensions on said motors, and boxes,axles adapted to said boxes, platforms at each end of the locomotive,connecting-rods coupling the cabs to the extensions of the motors sothat the draft will be from the driving-axle to the platform through aconnecting-rod, substantially as described.
